Unwearied still, lover by lover, / They paddle in the cold, / Companionable streams or climb the air; / Their hearts have not grown old; / Passion or conquest, wander where they will, / Attend upon them still.

The Wild Swans at Coole

William Butler Yeats

Yeats was the leader of the Irish literary renaissance that aimed at reviving ancient Irish folklore, legends and traditions in new literary works. The influence of the Celtic Renaissance is strong in Yeatss early poetry in which the poems often center on Irish mythology and themes and are mystical, slow-paced and lyrical.
